CHARLES E. SANFORD, -OF BROOKLYN, NFV YORK.

WATCHMANS REGISTER.

SPECIFICATION forming part of Letters Patent No. 285,952, dated October 2, 1883.

Application filed March 10, 1383.

T0 all wtmn, t may concern:

Be it known that I, Crmnnns E. SANFORD, of Brooklyn, New York, have invented a certain Improvement in Vatchmens Registers, of which the following is a specification.

My invention relates to the class of watchmens registers in which the clock mechanism which rotates the record-card automatically varies the position of the puneturing-pin at prescribed intervals of time, and also releases a shield which covers the key-hole of the lock upon the door of the case, and thus prevents the insertion of the key during a'prescribed period ot' time after the apparatus has been adjusted and set into action, as more fully shown and described in Letters Patent of the United States No. 261,388, dated July i8, 1882, granted to me for an improvement in watchmens registers.

My present invention consists, tirst, in the employment, in connection with the key-hole shield, of a spring-catch and an arm connected with the slide that carries the puneturing-pin, by the operation oi' which the key-hole shield is fastened over the key-hole; secondly, in the employment, in .connection with the springlatch of the lock upon the door of the apparat'is, of aguard-stop, also operated by the arm projecting from the slide which carries the puncturing-pin, by which the unlocking of the door of the apparatus is prevented, except at the close of the period ot' time for which the apparatus is designed or adjusted to act.

The third feature of my invention consists in so arranging the vertical slide which carries the puneturing-pin with relation to the disk atlixed to that portion ofthe shaft of the push-button which is within the door that when the slide is raised and the push-button is pushed in under the outer end of the puncturing-pin the slide will be held at such an elevation as to hold the guard-stop out of engagement with the latch or spring-bolt of the lock during the act ot'closing the door 5 fourthl y, in the apparatus illustrating my invention (shown in the accompanying drawings) an eight-day clock is employed, and the disk is provided with eight circles for receiving, respectively, punetures on eight successive days-as, for example, from Monday to Monday, both inclusive.

(Modehl The mechanism for automatically releasing and allowing access to the lock for the purpose of opening 'the door may be adjusted to act at the expiration of any part of a week after the door is closed. To guard against the possibility of any undiscovered tampering with the clock-movement or record-disk by the introduction ot' a slender pin through a small hole which might be drilled or bored in the shell of the ease, I line the top, bottom, and sides or" the interior ot' the ease with plateglass.

The drawings are as follows: Figure l is an elevation ofthe case which contains the apparatus with the door open, showing the disk, and showing the puncturing mechanism and lock in rear elevation. In this view the keyhole shield is represented as having been pushed across the key-hole, and its position, when thrown out bythe spring which retracts it, is represented in dotted lines. Fie'. 2 is a transverse vertical section of the apparatus with the door closed, the plane of section being through the axes ofthe puncturing-pin and push-button on the line x x, Fig. l. Fig. 3 is a transverse vertical section through the line 1/ 1/ on Fig. l, looking toward the inner side ot' the lock, showing the spring-latch, which holds the key-hole shield in the position which it occupies when the key-hole shield has been pushed in and stands across the key-hole. Fig. 4 is a horizontal section through the line z c on Fig. l, showing the relation of the guardstop to the spring-latch ofthe lock, and affording a top view ot' the puncturing mechanism. Fig. 5 is an elevation showing the inside of the lock, and Fig. 6 is a transverse section ot the lock through the line 10 w on Fig. 5. Fig. l* is a detached section of a portion ofthe mechanism for varying the position ofthe puncturing-pin. Fig. 2i: is a side elevation ot' a portion ot' the arborwhich carries the recorddisk, showin g the nut and washer by which the record-disk is secured to the arbor in section, and showing a portion of the record-disk in section.

The apparatus shown in the drawings is inelosed in a case, A, which is intended to be atiixed to the wall by screws a a, inserted through the back of the case, to which access can only be -had when the door B of the case IOO is open. The top, bottom, and sides of the inpanel of the door. A washer-preferably of terior of the ease are lined with the plates of thin india-rubber-is introduced between the glass A A A A.

Aixed to the interior of the case is a clockmovement, C, which is timed to rotate the arbor c once in twenty-four hours. The record `disk or dial Dis made of paper, and is clamped against acollar, c?, secured to the arbor c by the washer c* and clamping-nut c. The collar c2 is aixed upon the arbor by the set-screw c5, and is provided with a key-pin, c", which projects outwardly from the disk and into a hole, cl, formed in the washer c3. By this means the record-disk and the washer c are made to rotate with the arbor c. A suitable portion of the disk is ruled with concentric lines to provide eight annular spaces, of equal width, to receive the punctures or other marks made in the course of the use of the apparatus during eight successive days. One half of the disk, on one side of the diametrie'al line d, is tinted or marked to indicate night, while the other half is otherwise marked to indicate day. A tooth, es, projects from the face of the washer c", and serves, during 011e part of its revolution--that is, once in each day-to actuate a spring driving-pawl, E, which is pivoted in a frame supported upon the door, and which, bythe closing of the door, is brought into suitable proximity to the disk, so that a pin, E', projecting laterally from its lower end, projects into the path of movement of the tooth o8. v

rIhe object of having the crank-pin actuate the pawl E once a day is to lower the puncturingpin, so that its punetures during the ensuing day can be made in the circle next adjoining vthe circle containing the punctures of the preceding day. This is accomplished by mounting the reciprocating puncturing-pin F in a vertical carriage, G, which slides freely up and down in the guideways H, but is under a constant downward pressure due to the tension of the coiled spring, I aixed to the side of the door, the free end fi of which bears upon the grooved side of the head of a hollow screw, i', which is inserted in the inner face of the carriage G. The'carriage G is provided with a laterally-projecting pin, g, which bears upon the upper edge of the sliding tumbler J. The lower edge of the tumbler J is provided with the ratchet-teeth J', with which the upper end of the aetuating-pawlE'engages. The upper edge of the tumbler `J is formed into a series of shoulders, J 2, for affording bearings for the pin g at different elevations, corresponding with the elevations required for the puneturing-pin. Each throw of theactuating-pawl E is suficient to move the tumbler far enough to enable the pin g to drop from one shoulder of the tumbler to the next lower shoulder. When the door is closed the punct-l uring-pin is made to puncture the record-disk by pressing inward the push-button K, the shank of which is contained in the hollow bolt L, inserted through a suitable hole in the glass glass panel and the head L of the bolt L. A similar washer is introduced between the i11- ner surface of the glass and the frame M,which supports the guideways G and to the lower part of which the actuating-pawl E is pivoted. The inner portion of the ,hollow bolt L projects through a hole in the back Y plate, M', of the frame M, and is provided with a screwthread to receive the clamping-nut L2, by means of which the frame Mis firmlyfastened upon `the'inside of the glass panel. The inner end of the push-button is provided with the disk K, which bears upon the convex sides of the curved flat springs k k, supported, respectively, upon the inner sides of the guideways G. These springs yield when the pushbutton is pressed inward, and bytheir recoil force the push-button outward. When the push-button is pressed, the disk K strikes lagainst and drives inward ythe puneturing-pin 1F, which is retracted, when the push-button `is relieved from pressure, by the retractingspring f, bearing upon the collar f upon the inwardly-projecting part of the puncturingpin F.

To operate thevcatch for the key-hole guard, and also to operate the guard-stop for the latch of the lock, I provide the laterally-projecting arm N, which at one end is rigidly affixed to the carriageG, and at the other end carries the guard-stop O, which, as will be seen, during the greater part of its path of vertical motion, bears against the shoulder P, form ed upon the latch p of the look affixed to the door of the apparatus, and thereby stops the 4latch from being retracted. When the door is open the carriage G may be raised suillciently highl to carry the stop O above and out of engagement with the shoulderP, and in that position, if the push-buttn is thrust inward so that the outer endof the puneturing-pin rests upon the edge ofthe disk K, the guard-stop O will be held out of engagement with the shoulder P, so that the spring-latch p can be pushed into the lock by the act of closingthe door. When the door has been closed the push-button is relieved from pressure and springs outward, thus allowing the carriage to fall until the piu g is caught upon the upper edge of the tumbler. The latch p having sprung outward, or having been forced outward by the action of the key, if the lock is a dormant lock instead of being a spring-lock, the stop O falls downward behind the shoulder P, and thereafter prevents thedoor from being unlocked IOO IIO

until, by the repeated actuations of the pawl E. the tumbler J has been moved back so that the pin g rests upon thelowest shoulder, j, of the tumbler. In that position the stop O is carthus raising the outer end of the spring-catch Q, and permitting the key-hole shield R, under the iniiuence of its retracting-spring r, to spring backward into the position shown in dotted lines in Fig. l, thus allowing access to the key-hole for the insertion of the key to unlock the door.

In setting the apparatus for action, the carriage G is raised and the tumbler J is pushed back until its highest shoulder, jl, is brought under the pin g. The key-hole shield R is then pushed in across the key-hole, thus compressing its retracting-spring r, and is held in that position by the springing behind it of the outer end of the spring-catch Q under the influence of its retracting-spring q.

lt will be seen that the number of shoulders, j and j tojl, inclusive, for affording the bearings in which the carriage G is held at different elevations corresponds to the number of circles upon the record-disk.

By adjusting the tumbler J so that the pin g, which supports the carriage, bears upon the highest shoulder, jl, of the tumbler, the interior of the apparatus will be inaccessible for one week after the door is closedthat is, from the hour of closing the door upon one day to the same hour upon the eighth day thereafter-as, for example, from Monday to Monday, both inclusive.

rlhe outermost circle upon the record-disk is intended for the puncturcs made during the lirst twenty-'lbur hours after the door is closed, and the next adjoining circle for thepunctnres made during the next following twenty-four haur's, and so on, until, at the end ofthe seventh day, the pin g, supporting the carriage G, drops upon the shoulder j, thus releasing the lock, so that the door can be opened and the disk changed. lf, however, the disk' should not be changed, as may be the case if the day is a holiday, the record for that day will be made by punctures in the inner.' circle.

It' access to the interior of the apparatus is desired at shorter intervals-as, i'or example, every day-thc necessary adjustment for ai'- i'ording such access consists merely in so arranging the tumbler that the pin y, which supports the carriage G, rests upon the shoulder' Il' it be desired to have the door remain closed two days, the tumbler will be so adj usted as to have the pin g bear upon the shoulder f. ll" the door is to remain closed three days, the tumbler will be so adjusted as to have the pin g bear upon the shoulder j, and so on.

It will oi' course be understood that the apparatus may be arranged to act Vfor a longer period by increasing the number of circles upon the record-disk and correspondingly increasing the number' ot' shoulders upon the tumbler J and the range of movement ol' the carriage G, and by substituting for the eightday clock employed in the apparatus a clock running for the longer period desired.

If desired, there ma)` be substituted, in place of the spring-lock shown, either a dormant lock or a simple knob-latch, in either of which cases thekey-hole shield will of course be dispensed with, and the guard-stop will alone be employed to prevent the unlocking or unlatching o1 the door during the prescribed period of time for which the apparatusv may be adjusted to operate.

The mechanism for controlling the guardstop may also, if desired, be embodied in that class of watchmens lregisters in which, by means of electric circuits, the different circles upon the disk are respectively punctured by the actuation of push-buttons at dii'i'erent stations. ln this case, and in all cases in which access to the interior of the apparatus is required every twenty-tour hours, the mechanism for changing the position of the puncturing-pin with relation to the record-disk may be dispensed with, and the tooth upon the arbor which rotates the record-disk may be made to act positively upon the slide or upon the pivoted lever carrying the guard-stop. The preferable method ol" operating the guardstop, however, is substantially that shown in the drawings, in respect ofthe particular that the rotating tooth is only required to actuate a pawl or trigger, which releases the instrumentality carrying the guard-stop tothe action of a spring tending to force it downward, and thus carry the guard-stop out oi" engagement with the latch or bolt ot' the lock.
